Hi guys, If you have some time I would love to hear your opinion on the following design uploaded on ThemeForest - PSD Templates. They were both hard rejected for quality standard reasons.

It’s not bad -

I assume you also have different layouts, individual post pages by type e.g. single/multiple image, video, quote etc. etc.

Probably the biggest challenge for you is that this design exists already (and coded) quite a bit so you are going to need to find layouts and designs that really make it stand out.

With respect, ou are in the right way, but this is not enough.
Just check out the latest thems and check your https://themeforest.net/category/site-templates

Try, study and move forward - this is the main advice
